Metaphors and Similie

Similes and metaphors both compare two different things to create a vivid image, but one small structural detail — the presence or absence of 'like' or 'as' — is exactly what separates them, and exactly what exams test.

Learning objectives

  • Define a simile and recognize its structure using 'like' or 'as'
  • Define a metaphor and recognize its direct, implicit structure
  • Correctly distinguish a simile from a metaphor in a given sentence
  • Identify well-known examples of both devices without mislabeling them
  • Explain the effect a simile or metaphor creates in a text
  • Create original similes and metaphors using the correct structure

Grammar & vocabulary

Simile — comparison using 'like' or 'as'

A simile is a figure of speech that compares two different things explicitly, using the word 'like' or the structure 'as... as'. The comparison word is always present and visible in the sentence. "Her smile was as bright as the sun." "He runs like the wind." "Life is like a box of chocolates." "The old man's hands were as rough as sandpaper."

Metaphor — direct comparison, no 'like' or 'as'

A metaphor is a figure of speech that compares two different things directly, without using 'like' or 'as' — it states that one thing IS another, rather than saying it is similar to it. "Time is money." "Her heart is a block of ice." "The classroom was a zoo." "Life is a journey." Because there is no explicit comparison word, the comparison is implicit — the reader has to understand that the sentence is figurative, not literal (a classroom is obviously not a real zoo).

The key structural difference

The test that reliably distinguishes the two: does the sentence contain 'like' or 'as... as'? If yes, it is a simile. If the sentence instead uses a form of the verb 'to be' (is, was, are, were) to directly equate two different things, it is a metaphor. Simile: "Her smile was as bright as the sun." (explicit comparison word 'as... as') Metaphor: "Her smile was pure sunshine." (direct, implicit equation, no comparison word).

Why writers use them

Both devices make descriptions more vivid and memorable than plain, literal language by connecting an abstract or ordinary idea to something familiar and concrete, helping the reader picture it more clearly and feel its meaning more strongly. Because a metaphor states the comparison as a direct equation rather than a similarity, it can feel bolder and more emphatic than a simile describing the same idea.

Common mistakes

1

Calling any comparison a 'metaphor' even when it uses 'like' or 'as' — if the sentence contains 'like' or 'as', it is a simile, not a metaphor; 'She is like a rose' is a simile, not a metaphor.

2

Believing a metaphor is 'weaker' or less direct than a simile — the opposite is true; a metaphor states something IS something else directly, which is often a stronger, bolder comparison than a simile.

3

Confusing a literal statement with a metaphor — 'The classroom was noisy' is a plain, literal statement, not a metaphor; 'The classroom was a zoo' is the metaphor, because a classroom is not literally a zoo.

4

Misspelling or mispronouncing 'simile' as 'similie' or 'similar' — the correct spelling of the literary device is 'simile' (three syllables: sim-i-lee), not 'similie.'

5

Forgetting that both devices compare two essentially different things — comparing two very similar things ('This orange tastes like that other orange') is not a simile or metaphor in the literary sense; the comparison should connect two different categories of things to create a vivid image.

Worked example — A description of a storm

Passage

"The sky turned as dark as ink, and the wind howled like a wounded animal. By the time the storm reached the village, it was a raging monster, tearing roofs from houses. The rain fell like a thousand tiny hammers on the windows, and the thunder was a drumbeat announcing danger. Afterward, the streets were rivers, and the silence that followed felt as heavy as a blanket."

Explanation

"as dark as ink" and "like a wounded animal" are similes — both use explicit comparison words ('as... as' and 'like'). "it was a raging monster" and "the thunder was a drumbeat" are metaphors — both directly equate the storm and the thunder with something else, without 'like' or 'as'. "like a thousand tiny hammers" is a simile ('like'). "the streets were rivers" is a metaphor, stating directly that the streets (temporarily, figuratively) were rivers. "as heavy as a blanket" is a simile ('as... as'). This mix shows how both devices can work together to build a vivid, emotional description.

3 practice exercises

Exercise 1

Easy

Decide whether each sentence is a simile or a metaphor. 1) 'He runs like the wind.' 2) 'Time is money.' 3) 'Her heart is a block of ice.' 4) 'The old man's hands were as rough as sandpaper.'

Show answer

1) Simile (uses 'like'). 2) Metaphor (direct comparison, no 'like'/'as'). 3) Metaphor (direct comparison, no 'like'/'as'). 4) Simile (uses 'as... as').

Exercise 2

Medium

Complete each sentence to form the type of comparison indicated. 1) (Simile) 'The night sky was as dark as ___.' 2) (Metaphor) 'The internet is a ___.' 3) (Simile) 'She sings like a ___.' 4) (Metaphor) 'His words were ___ that cut deep.'

Show answer

1) 'as dark as ink' / 'as dark as coal' (any vivid, dark image works, using 'as... as'). 2) 'a vast ocean of information' (any direct comparison stating the internet IS something, no 'like'/'as'). 3) 'nightingale' / 'bird' (any vivid image, using 'like'). 4) 'knives' / 'daggers' (any direct comparison, no 'like'/'as').

Exercise 3

Hard

Rewrite each literal sentence as first a simile, then a metaphor, describing the same idea. 1) 'The wind was very strong last night.' 2) 'My grandmother is very wise.'

Show answer

1) Simile: 'The wind howled like an angry beast last night.' Metaphor: 'The wind was a roaring beast last night.' 2) Simile: 'My grandmother is as wise as an owl.' Metaphor: 'My grandmother is a fountain of wisdom.'

FAQ

What is the difference between a simile and a metaphor?

A simile compares two things explicitly using 'like' or 'as': 'Her smile was as bright as the sun.' A metaphor compares two things directly, without 'like' or 'as', by stating that one thing is another: 'Her smile was pure sunshine.' The presence or absence of 'like'/'as' is the key structural difference between the two.

Can you give a well-known example of a metaphor?

A classic example is 'Time is money' — this states directly that time IS money, without using 'like' or 'as', to emphasize that time is valuable and should not be wasted. Another common one is 'The classroom was a zoo,' meaning the classroom was extremely noisy and chaotic.

Why do writers use similes and metaphors?

Writers use similes and metaphors to make descriptions more vivid, memorable, and emotionally powerful than plain, literal language. Comparing an abstract or ordinary idea to something familiar helps the reader picture it more clearly and feel its meaning more strongly.
